------------------------------
Summary: improve the average latency precision of the metrics log
Key: SCB-1210
URL: https://issues.apache.org/jira/browse/SCB-1210
Project: Apache ServiceComb
Issue Type: Improvement
Reporter: YaoHaishi
Assignee: YaoHaishi
For a long statistical period and low tps situation, for example, metrics
period is 60 sec and there are only two invocation each costs 1.5 second to
process. The metrics log print the max latency correctly(1500ms), but the
printed average latency is 0.
The cause is that a int variable is used to calculate the tps distributed into
every second and the average latency is calculated by (tps distributed into
every second)/(total latency distributed into every second). And in such
situation, the tps data distributed to every second is 0, so the average
latency is 0.
The tps data should be stored in a double variable and the metrics log format
should be adjust slightly.
